How to Reduce Image Resolution in Python Without Resizing

Summary: Learn how to perform image processing in Python using OpenCV to reduce the resolution of an image without resizing it.
---

Reducing the resolution of an image can be a necessary task in a variety of applications, such as preparing images for analysis or decreasing file size for storage. In this guide, we'll explore how you can reduce the resolution of an image in Python using the powerful OpenCV library without actually resizing its dimensions.

Understanding Image Resolution

Resolution refers to the detail an image holds and is often described by the width and height in pixels. However, it can also refer to the pixel density, which affects the image clarity. Reducing resolution while maintaining the same dimensions of the image involves decreasing the pixel density, which in turn lowers the detail.

Using OpenCV in Python

OpenCV (Open Source Computer Vision Library) is a popular library for image processing in Python. Let's dive into the steps required to reduce the resolution of an image.

Steps to Reduce Image Resolution

Import Necessary Libraries: First, ensure you have OpenCV installed. You can install it using pip if you haven't already:
